The detection is possible for

position indicator for fan flaps


Air Quality Sensor LGS/A 1.1Comfortable room climate

People raise the CO2 concentration in the air when they breathe:

Normal room air has about 21% Oxygen (O2) and about

0.035 % Carbon Dioxide (CO2)

However, during exhalation the air only contains about 16 % O2 (reduction of about 24 %), but 4 % CO2 (a more than 100-fold increase!)

In addition to the CO2 concentration, the relationship between room temperature and humidity is also an important consideration in achieving a comfortable room climateComfortable room climate in dependence

on the room temperature and humidity

Heating and Cooling Which control system ???

RadiatorPWM (cycle time 15 minutes) or 2-point control

Underfloor/Wall HeatingThis system reacts very slowly, therefore, a PWM control with a cycle time of 20 - 30 minutes is appropriate

Hot water Fan HeatersIn this case, the hot-water circuit is controlled. A continuous control is ideal. As a result, the temperature of the air stream remains relatively constant.

Electric convector HeatersPWM control and cycle time 15 minutes

Fan Cooling Continuous PI control, change for automatic transmission: 5%

Thermoelectric Valve Drive TSA/K

Function The resistor-heated elastic element ① is heated and expands by applying the operating power

The integrated ram ② performs the adjustment travel

The adjustment travel (approx. 4 mm) is transformed to the valve lifter ③

The valve will be opened or closed.The function display ④ shows valve status
